KC705: vivado 2015.4 cannot find the device when open hw.

[chunyan]

when using vivado 2015.4 to open hw target, it shows the error below.

//===============================================================================

INFO: [Labtools 27-2285] Connecting to hw_server url TCP:localhost:3121

Check cable connectivity and that the target board is powered up then
use the disconnect_hw_server and connect_hw_server to re-register this hardware target.
ERROR: [Labtools 27-55] Invalid index 0 passed to getDevice

Vivado can find KC705 board serial number but cannot find hardware device. 

could anyone help? thank you.

Hi @chunyan,

I haven't ever used the KC705 but like you said, Vivado seems to be detecting the on-board Digilent programmer correctly (I presume you already installed the cable drivers). I would recommend taking a look at these two Xilinx threads: https://support.xilinx.com/s/question/0D52E00006iHlecSAC/vivado-kc705-jtag-no-devices-detected-on-target?language=en_US and https://support.xilinx.com/s/question/0D52E00006hpfQwSAI/vivado-hardware-manager-doesnt-see-device?language=en_US.

Thanks,
